_To enform you of the Advantages of the present Impression, and disabuse your expectations of any future Enlargements; these are to advertise thee, that this Edition comes forth with very many Explanations, Additions, and Alterations throughout, besides that of one entire Chapter: But that now this Work is compleat and perfect, expect no further Additions._ THE FIRST BOOK OR GENERAL PART CHAPTER I Of the Causes of Common Errors. [Sidenote: _The Introduction._] The First and Father-cause of common Error, is, The common infirmity of Human Nature; of whose deceptible condition, although perhaps there should not need any other eviction, than the frequent Errors we shall our selves commit, even in the express declarement hereof: yet shall we illustrate the same from more infallible constitutions, and persons presumed as far from us in condition, as time, that is, our first and ingenerated forefathers. From whom as we derive our Being, and the several wounds of constitution; so, may we in some manner excuse our infirmities in the depravity of those parts, whose Traductions were pure in them, and their Originals but once removed from God. Who notwithstanding (if posterity may take leave to judge of the fact, as they are assured to suffer in the punishment) were grossly deceived, in their perfection; and so weakly deluded in the clarity of their understanding, that it hath left no small obscurity in ours, How error should gain upon them. [Sidenote: _Matter of great dispute, how our first parents could be so deceived._]
